Is widevine supported on xbox inside WebView2?

[stavfx]

I'm trying to wrap an existing app inside WebView2, and window.navigator.requestMediaKeySystemAccess is coming up as undefined.
I'm wondering if I'm missing a config, or it's not currently supported

I don't know if this fully answers why window.navigator.requestMediaKeySystemAccess is undefined, but this isn't really a WebView2 problem, xbox doesn't support Widevine, only PlayReady: https://learn.microsoft.com/en-us/windows/uwp/apps-for-xbox/supported-technologies#drm
